Dispose problem in destructor

Hello,

Problem with dispose in destructor ... (10.2B SP 4)

This is the situation :

* base form : base.cls,  has a components area

* custom specific form, inherits fomr base form) : has its own components area

In the destructor of both forms, there is following generated code :

        if valid-object(components) then do:
             cast(components, System.IDisposable):Dispose().
        end.

When I debug, I first go in the destructor of the custom specific form, no problems here ...

Following, I go into the destructor of the base ... I get an error on the end statement (thus not on the dispose method) :

System.ObjectDisposedException: Cannot access a disposed object.

However, the components was a valid object ...

Anyone an idea where to look for.

I tried to reproduce the error in a small test form, and was not able to reproduce it there ...

I compared the destructors, initializecomponent of each form, but I could'n t see a possible mistake
